if you have a fast processor and run it in a decently fast browser like opera or safari it might actually be fast enough to be useful.
on my computers here it's horribly slow in firefox (freebsd and windows xp), slightly better in konqueror (freebsd) and IE 7 (windows xp), and almost fast enough to be useful in opera (freebsd and windows xp) and safari (windows xp). and these machines are all more than 2 years old.
